Solenoid hissing

Hey everyone, just got my Luxe 2.0 back from GoG and when I went to the field to play it was half cycling and at times just flat out not working; "puffing" almost. So I spent the day at the field changing out all the o-rings on my pooty core, threw in my stock core also, and nothing seemed to fix the problem. Then later that night I went home and tried just slowly turning up the reg and all of a sudden it started to leak from the grip frame near the solenoid/trigger. Then all of a sudden it started to hiss from the solenoid, so I quickly lowered the pressure and turned the gun off. I was wondering if anyone had any suggestions to remedy this problem before I call DLX and see what they can do for me.

Ok, that's what I was kind of guessing it was last night before I went to bed. I'll take the reg apart after I get out of classes and finish work. Thanks for the help guys, I'll post the outcome later tonight.
